Prices for AMD R600 series revealed

While there's not an official statement from AMD, according to some the final prices for R600 series based cards are now available. The prices are pretty much exactly what you'd expect, ranging from $99 at the low end for the R610, $199 at the midlevel for the R630XT and upwards of $499 for the high end models. Now we wait to see what the different vendors will be offering. Hopefully AMD will confirm these prices soon, though I wonder how they intend to intend to compete with Nvidia if not on price. Could R600 really be that stellar in terms of performance?
